Answer:
  12     :    3      :    1
white : yellow : green
Explanation:
Given that genes A and B control the fruit colour in following ways:
A_B_ or A_bb = white
aaB_ = yellow
aabb =  green
The genes undergo independent assortment so:
AaBb X AaBb =
A_B_ : A_bb : aaB_ : aabb 
   9     :    3     :   3      :   1
white : white : yellow: green
         12          :    3     :   1
Hence, ratio of white : yellow : green is 12: 3: 1
